The following formulas give the enthalpy, when Coal and Methane react with oxygen: C+O2->CO2+394 kJ/mol, 12 gram C gives 44 gram of CO2+394 kJ CH4+ O2->CO2+2H2O+891 kJ/mol, 16 gram CH4 gives 44 gram of CO2+891kJ   a)     Calculate the heating value of Coal and Methane in MJ/kg and in kWh/kg. b)     Calculate the amount of CO2 which is produced per kWh for Coal and Methane. Give it in kg/kWh.
